General Description
Features
The IDT8N0DV85 is a LVCMOS Dual-Frequency Programmable
VCXO with very flexible frequency and pull-range programming
capabilities. The device uses IDT’s fourth generation FemtoClock®
NG technology for an optimum of high clock frequency and low
phase noise performance. The device accepts 2.5V or 3.3V supply
and is packaged in a small, lead-free (RoHS 6) 6-lead ceramic 5mm
x 7mm x 1.55mm package.
• Fourth generation FemtoClock® NG technology
• Programmable clock output frequency from 15.476MHz to
260MHz
• Two factory-programmed output frequencies
• Frequency programming resolution is 218Hz and better
• Absolute pull-range (APR) programmable from 4.5 to
754.5ppm
The device can be factory-programmed to any two frequencies in the
range of 15.476MHz to 260MHz to the very high degree of frequency
precision of 218Hz or better. The output frequency is selected by the
FSEL pin. The extended temperature range supports wireless
infrastructure, telecommunication and networking end equipment
requirements.

Principles of Operation
Frequency Configuration
The block diagram consists of the internal 3RD overtone crystal and
oscillator which provide the reference clock fXTAL of 114.285MHz.
The PLL includes the FemtoClock NG VCO along with the
Pre-divider (P), the feedback divider (M) and the post divider (N). The
P, M, and N dividers determine the output frequency based on the
fXTAL reference. The feedback divider is fractional supporting a huge
number of output frequencies. Internal registers are used to hold up
to two different factory pre-set configuration settings. The
configuration is selected via the FSEL pin. Changing the FSEL
control results in an immediate change of the output frequency to the
selected register values. The P, M, and N frequency configurations
support an output frequency range 15.476MHz to 260MHz.
An order code is assigned to each frequency configuration and the
VCXO pull-range programmed by the factory (default frequencies).
For more information on the available default frequencies and order
codes, please see the Ordering Information Section in this document.
For available order codes, see the FemtoClock NG Ceramic-Package
XO and VCXO Ordering Product Information document.
For more information on programming capabilities of the device for
custom frequency and pull-range configurations, see the FemtoClock
NG Ceramic 5x7 Module Programming Guide.
The devices use the fractional feedback divider with a delta-sigma
modulator for noise shaping and robust frequency synthesis
capability. The relatively high reference frequency minimizes phase
noise generated by frequency multiplication and allows more efficient
shaping of noise by the delta-sigma modulator. The output frequency
is determined by the 2-bit pre-divider (P), the feedback divider (M)
and the 7-bit post divider (N). The feedback divider (M) consists of
both a 7-bit integer portion (MINT) and an 18-bit fractional portion
(MFRAC) and provides the means for high-resolution frequency
generation. The output frequency fOUT is calculated by:

Schematic Layout
Figure 1 shows an example of IDT8N0DV85 application schematic.
In this example, the device is operated at VCC = 3.3V. The schematic
example focuses on functional connections and is intended as an
example only and may not represent the exact user configuration.
Refer to the pin description and functional tables in the datasheet to
ensure the logic control inputs are properly set. For example FSEL
can be configured from an FPGA instead of set with pull up and pull
down resistors as shown.
As with any high speed analog circuitry, the power supply pins are
vulnerable to random noise, so to achieve optimum jitter performance
isolation of the VCC pin from the power supply is required. In order to
achieve the best possible filtering, it is recommended that the
placement of the filter components be on the device side of the PCB
as close to the power pins as possible. If space is limited, the 0.1µF
capacitor on the VCC pin must be placed on the device side with
direct return to the ground plane though vias. The remaining filter
components can be on the opposite side of the PCB.
The typical application of the IDT8N0DV85 is a voltage-controlled
oscillator as part of a PLL. The two connections necessary to be
made to the PLL are VC, the analog control voltage that sets the
center frequency of the VCXO, and Q, which is the oscillator output.
VC is the analog output of the PLL low pass loop filter that serves to
remove noise from the phase detector error output.
Power supply filter component recommendations are a general
guideline to be used for reducing external noise from coupling into
the devices. The filter performance is designed for a wide range of
noise frequencies. This low-pass filter starts to attenuate noise at
approximately 10kHz. If a specific frequency noise component is
known, such as switching power supplies frequencies, it is
recommended that component values be adjusted and if required,
additional filtering be added. Additionally, good general design
practices for power plane voltage stability suggests adding bulk
capacitance in the local area of all devices.
In order to achieve the best possible filtering, it is recommended that
the placement of the filter components be on the device side of the
PCB as close to the power pins as possible. If space is limited, the
0.1µF capacitor in each power pin filter should be placed on the
device side of the PCB and the other components can be placed on
the opposite side.

Power Considerations
This section provides information on power dissipation and junction temperature for the IDT8N0DV85.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the IDT8N0DV85 is the sum of the core power plus the power dissipation in the load(s). The following is the
power dissipation for VCC = 3.3V +5% = 3.465V, which gives worst case results.
•
Power (core)MAX = VCC_MAX * ICC= 3.465V * 163mA = 564.8mW
Total Static Power:
= Power (core)MAX = 564.8mW
Dynamic Power Dissipation at FOUT (max)
Total Power (FOUT_MAX) = [(CPD * N) * Frequency * (VCC)2] = [(8pF *1) * 260MHz * (3.465V)2] = 25mW
Total Power
Total Power
= Static Power + Dynamic Power Dissipation
= 564.8mW + 25mW
= 589.8mW
2. Junction Temperature.
Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad, and directly affects the reliability of the device. The
maximum recommended junction temperature is 125°C. Limiting the internal transistor junction temperature, Tj, to 125°C ensures that the bond
wire and bond pad temperature remains below 125°C.
The equation for Tj is as follows: Tj = θJA * Pd_total + TA
Tj = Junction Temperature
θJA = Junction-to-Ambient Thermal Resistance
Pd_total = Total Device Power Dissipation (example calculation is in section 1 above)
TA = Ambient Temperature
In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance θJA must be used. Assuming no air flow and
a multi-layer board, the appropriate value is 49.4°C/W per Table 6 below.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.590W * 49.4°C/W = 114.1°C. This is below the limit of 125°C.
This calculation is only an example. Tj will obviously vary depending on the number of loaded outputs, supply voltage, air flow and the type of
board (multi-layer).
